The curly braces seem to be the set-builder notation,
I dont know where to post this question. In information theory Capacity C = max{I(Xk;Yk) : E[Xk^2]=P} where maximization is wrt probability fx prob. density fn of Xk. What does this value C equals? Can anyone explain that notation. -Devanand T

My best guess is this: maximize the mutual information between Xk and Yk, subject to the constraint that the expected value of Xk^2 is P.
As far as I know (I don't know much about channel capacity), the part about the expected value of Xk^2 is not part of the standard definition of channel capacity. See, for example, Channel capacity - Wikipedia, the free encyclopedia
